The Tour de Suisse Women 2026 reaches its most precise test on Saturday, 20th June, with the stage 4 individual time-trial in Aarburg. After three road stages shaped by attacks, selective finales and a sprint opportunity in Bad Ragaz, the race now moves into the discipline that should have the biggest impact on the general classification before the final mountain stage.
Aarburg to Aarburg is 23.8km, giving the strongest riders against the clock enough distance to create real separation. It is not a mountain time-trial, but it is long enough to punish riders who cannot hold position, pace the effort properly or keep speed through the technical sections.
Elisa Longo Borghini starts the day with the race lead after her decisive stage 2 attack in Locarno, but this is the stage Marlen Reusser has been waiting for. The Swiss rider remains the clearest time-trial reference in the field, and with the final mountain stage still to come in Villars-sur-Ollon, Aarburg could decide who is defending and who is forced to attack on Sunday.

What time does Tour de Suisse Women 2026 stage 4 start?
Stage 4 of the Tour de Suisse Women 2026 takes place on Saturday, 20th June.
The women’s individual time-trial is scheduled to begin at 10:45 local time in Switzerland. That is 09:45 in the UK. The final rider is expected to finish at around 12:45 local time, which is 11:45 in the UK.
That makes it a morning viewing slot for UK fans, with the key general classification riders likely to be on course towards the end of the session. As always with time-trials, the main drama will come from the start order, intermediate splits and whether an early benchmark can survive the final wave of GC contenders.
Tour de Suisse Women 2026 stage 4 start time in the UK
The stage is due to start at 09:45 BST.
The final rider is expected to finish at around 11:45 BST.
UK viewers should check their live coverage platform before the first rider rolls down the ramp, as time-trial broadcasts do not always follow the same pattern as road-stage coverage. The most important GC riders should start later in the order, but early specialists can still set times that shape the stage.
How to watch Tour de Suisse Women 2026 stage 4 in the UK
UK coverage of the Tour de Suisse Women 2026 is available through TNT Sports’ cycling coverage, with streaming access through HBO Max following the Warner Bros. Discovery platform switch in the UK.
Because stage 4 is a morning time-trial, viewers should check the TNT Sports and HBO Max schedules early rather than assuming the race will sit in the usual afternoon cycling window. The women’s time-trial takes place before the men’s Aarburg time-trial later in the day, so the timing is easy to miss if you are only looking at the broader Tour de Suisse listing.
There is also free Swiss broadcast coverage of the Tour de Suisse, usually available in German, French and Italian, although access may depend on location and geo-restrictions. For UK viewers, TNT Sports and HBO Max remain the simplest legal routes to live coverage.
Why stage 4 is worth watching
Stage 4 should be one of the most important days of the 2026 Tour de Suisse Women. A 23.8km individual time-trial is long enough to create clear gaps, especially in a five-day race where there is only one mountain stage left afterwards.
Reusser has the most obvious route to a stage win. She has the home-road motivation, the power profile and the time-trial pedigree to take significant time from most of the GC field. If she produces the ride expected of her, she can either move into yellow or force Longo Borghini and the climbers into a much more aggressive final stage.
Longo Borghini’s task is different. She does not necessarily need to beat Reusser, but she needs to keep the gap manageable. Her Locarno attack gave her a strong platform, and a controlled time-trial in Aarburg would keep her firmly in the overall fight before Villars-sur-Ollon.
Zoe Backstedt is another obvious name to watch after winning stage 3 in Bad Ragaz. Her power and technical skill make her a real stage contender if she has recovered well. Riejanne Markus, Karlijn Swinkels, Loes Adegeest, Steffi Häberlin, Cédrine Kerbaol and Franziska Koch should also be among the riders capable of producing strong rides against the clock.
For Kasia Niewiadoma-Phinney, Kim Le Court, Sarah Van Dam and Liane Lippert, this is more about limiting losses than winning the stage. Each has a route into the final GC picture, but only if they stay close enough before Sunday’s mountain stage.
What happens after stage 4?
The Tour de Suisse Women 2026 finishes on Sunday, 21st June, with the final mountain stage in Villars-sur-Ollon. That makes the Aarburg time-trial even more important because it sets the tactical terms for the last day.
If Reusser gains a large margin, the final stage becomes a defensive exercise for Movistar and an attacking day for everyone else. If Longo Borghini limits her losses, UAE Team ADQ can continue to race from a position of strength. If Kerbaol, Niewiadoma-Phinney, Le Court or Van Dam stay close, the final stage could become much more open.
Aarburg will not finish the race mathematically, but it should make the final shape much clearer. The riders who leave the time-trial within range can still dream of winning the Tour de Suisse Women. The riders who lose too much will need something far more ambitious in Villars-sur-Ollon.
